Define 1 joule of work?

Question

Answer

1 joule of work is defined as the product of force of 1 Newton and a distance of 1 metre
W=F x s

Answer

1 jouse of work is said to be done when a force of 1 Newton is applied on a body and the body displaces by 1 Metre. It can be expressed as:W= F×s   = 1 N ×1 m   =1 Nm or 1 J

Answer

Work done = Force x Distance

The amount of work done when a force of 1 N (newton) moves a body through distance of 1 m towards the direction of force is equal to 1 joule.

1 Joule = 1 newton x 1 meter

Answer

Definition of 1 Joule of Work

Introduction:
In physics, work is defined as the transfer of energy from one object to another by applying a force over a certain distance. The unit of work is joule (J), which represents the amount of energy transferred when a force of one newton is exerted over a distance of one meter. To better understand the concept of 1 joule of work, let's break it down further.

Explanation:

What is a joule?
- A joule is the basic unit of energy in the International System of Units (SI).
- It is named after the English physicist James Prescott Joule, who contributed significantly to the study of energy.
- One joule is equal to the work done when a force of one newton is applied over a distance of one meter.

Understanding work:
- Work is the product of force and displacement in the direction of the force.
- Mathematically, work (W) can be calculated using the formula W = F × d, where F is the force applied and d is the displacement.
- When the force and displacement are in the same direction, positive work is done. If they are in opposite directions, negative work is done.

Visualizing 1 joule of work:
- To better understand the magnitude of 1 joule of work, consider the following examples:
- Lifting a small apple from the ground to a height of 1 meter requires approximately 1 joule of work.
- Pushing a box with a force of 1 newton for a distance of 1 meter also involves 1 joule of work.
- If a person walks 10 meters while exerting a force of 0.1 newtons in the direction of motion, the work done would be 1 joule (0.1 N × 10 m = 1 J).

Significance of 1 joule:
- The joule is widely used in various fields, including physics, engineering, and everyday life.
- It provides a standard unit for measuring energy transfer and work done.
- Understanding the concept of 1 joule helps us comprehend the energy requirements and the magnitude of work involved in different tasks or processes.

Conclusion:
In conclusion, 1 joule of work represents the amount of energy transferred when a force of one newton is exerted over a distance of one meter. This unit of work is fundamental in physics and helps quantify the energy requirements and work involved in various activities. By grasping the concept of 1 joule, we can better understand the magnitude of energy transfer and appreciate the role it plays in different aspects of our lives.
